The Office for National Statistics just released its bi-annual estimate of who exactly owns the shares in UK-listed and incorporated companies.
Foreign investors own the lion's share of £1.7 trillion ($2.6 trillion) worth of stock, according to the ONS, accounting for an estimated 54% of shares.
Individual, or retail, investors meanwhile own just 12% of shares. Still, that's up from a historic low of just 10% in 2010 and 2012.
Here's the full breakdown of who owns
Foreign ownership of UK shares has soared since the early 1990s from less that 20% to its current level.
Meanwhile, ordinary people putting their money directly into the stock market and owning shares has been falling since the 1960s.
The biggest foreign investors in UK shares are Americans. They account for 46%, or £929 billion ($1.4 trillion), of the 54% of foreign owned shares.
Pension funds are often talked about as big stock owners - when the FTSE goes up or down it's supposed to be good or bad for our pensions - but it turns out they only own around 3% of UK stock. That's a historic low.
Pension funds have been reducing their stock holdings since the early 1990s, coming down from a high of 32% ownership. The ONS says there's some evidence to suggest they've been switching to less volatile gilts in recent years.
Similarly, insurance companies have been rapidly reducing their stock holdings since the late 1990s.
Insurance companies have gone from a high of owning 24% of UK stock markets to just 6% in 2014.
